Build a custom touch surface from the KB-1 keyboard suite, an all-new sequencer suite, knobs, faders, buttons and more — then unlock a visual MIDI processing graph (one time in-app purchase) and wire it into anything, from a simple custom controller to a full-on groovebox or a self-playing generative composer. Play it on its own and send MIDI anywhere, as an AUv3 plugin in your favourite host or a standalone instrument. THE BASE APP — PERFORMANCE SURFACE Design a custom control surface on a snapping grid: • The KB-1 keyboard suite — piano, diatonic chord pads, scale-locked keyboard, MPE Seaboard ribbon, MPE Strings grid (4ths), and a 4×4 GM drum-pad grid. Each is its own routable node with latch and octave shift. Successor to the KB-1 Expressive Keyboard Suite. • A suite of sequencers — drum, melody, chord, analog and CC step grids and a Matrix note grid, with a moving playhead, swing and microtiming. Per-step velocity, probability, tie and trigger conditions; pattern chaining and 4-pad scene switching for full arrangements; a knob-per-step analog machine that re-roots live as you play. • Knobs, faders, XY pads, buttons and live visualizers — bind to raw MIDI CC or graph parameters. On its own: a rich custom control surface builder — send MIDI and CC to any synth, app or hardware, no graph required. WITH YOUR DESKTOP DAW Expressive MPE hardware costs hundreds. MIDIRack turns the iPad you already own into a controller for Logic, Live, Bitwig, Cubase or any desktop DAW: • Two MPE surfaces — the Seaboard ribbon and the Strings grid send per-note pitch bend, slide and pressure to any MPE-capable instrument on your desk. • A controller that changes per track — MPE ribbon for the lead, drum pads for the beat, chord pads for the progression, faders mapped to CC for a mix move. Rearrange in seconds; save a surface per project. • Sequence it too — clock the step lanes to your DAW and drive its tracks. • Easy to connect — one USB cable to a Mac via IDAM (Inter-Device Audio and MIDI), or wirelessly over Bluetooth MIDI. No driver, no helper app. UNLOCK — MIDI GRAPH (in-app purchase) Wire MIDI In → processors → MIDI Out on a visual canvas: • 60+ node kinds — arpeggiators, scale/key quantizers, transposers, chords, echoes, swing, humanize, euclidean rhythms, random/generative melodies, LFOs, CC tools, an analog knob-per-step sequencer, a Matrix sequencer and a Counter. • Built-in instruments — Synth, Drums, a Sampler and a loop Slicer make sound right in the graph; no external synth required. • Emergence generators — Conway's Game of Life, Turing machine, Wolfram rules, Markov, bouncing balls, Lorenz attractor — for evolving, living patterns. • Presets — factory patches grouped by category (control surfaces, generators, keyboards, utilities): Amen Engine, Starfield, Conway Choir, Turing Bass, Cellular Drums… Save your own. ROUTING & MPE • MIDI Out exposes all 16 channels plus an MPE connector — multitimbral, multi-instrument setups. The built-in synth responds to MPE. • Every keyboard is its own node — process and route each one independently. PLAYS OUT OF THE BOX • Built-in polyphonic synth, drum kit, sampler & slicer or send MIDI to your gear via CoreMIDI and an always-on virtual port. ## MIDIRack Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/7e/c4/d6/7ec4d62c-e7ca-27e7-35eb-32ffc926d906/01-hero.png/2778x1284.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/18/b9/1e/18b91e6d-b2dc-704f-f244-56671931fa30/02-build.png/2778x1284.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/23/34/77/233477d4-c437-e458-613e-2b06ee7e7a4a/03-patch.png/2778x1284.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/08/a7/39/08a73923-4498-63cb-4eeb-b9767d7ae980/04-play.png/2778x1284.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/0b/db/be/0bdbbe3b-ceac-070d-58da-b8f53fabb150/08-sequence.png/2778x1284.png) - [Screenshot 6](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/21/1d/50/211d509a-7f1c-7799-6031-d58b6a026aeb/09-controls.png/2778x1284.png) - [Screenshot 7](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/bd/d1/80/bdd18034-0eff-db2f-561c-d689762b6cdd/05-generative.png/2778x1284.png) - [Screenshot 8](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/fc/a5/54/fca5547a-731b-4fc4-da0b-55990496df7c/06-sound.png/2778x1284.png) - [Screenshot 9](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/62/4c/26/624c2609-63b3-682e-2f86-bbcf7b405c76/07-connect.png/2778x1284.png) ## MIDIRack Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Paid | Italy | Music | #8 | | Top Paid | Sweden | Music | #42 | | Top Paid | Japan | Music | #53 | | Top Paid | Italy | Overall | #60 | | Top Grossing | Italy | Music | #99 | ## MIDIRack Available In - [United States](https://apptail.io/app/midirack-NAAB/united-states) - [United Kingdom](https://apptail.io/app/midirack-NAAB/united-kingdom) - [Japan](https://apptail.io/app/midirack-NAAB/japan) - [Canada](https://apptail.io/app/midirack-NAAB/canada) - [Norway](https://apptail.io/app/midirack-NAAB/norway) - [Romania](https://apptail.io/app/midirack-NAAB/romania) - [South Africa](https://apptail.io/app/midirack-NAAB/south-africa) - [Switzerland](https://apptail.io/app/midirack-NAAB/switzerland) - [Italy](https://apptail.io/app/midirack-NAAB/italy) - [Netherlands](https://apptail.io/app/midirack-NAAB/netherlands) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
